SPECIFICATION forming part of Letters Patent No. 343,359,,dated June 8, 1886.

Application filed April 21, 1886.

To all whom it may concern:

Be it known that I, MIoHAEL J. BERRY, a citizen of the United States, residing at Bradford, in the county of McKean and 'State of 5 Pennsylvania, have invented certain new and 5 nomical and safe use, especially in dwellings,

can be secured only when it is at a pressure of a few ounces per square inch, and it is necessary that the pressure be uniform, whatever the original pressure may be. 7

This invention is intended to reduce the pressure of the gas automatically; and it consists in connecting the valve with afloat which will open and close the valve by the increase or diminution of the gas whenever the pressure rises above or falls below a certain point.

The drawing represents, partly in perspective and partly in vertical central section, an apparatus constructed in accordance with my invention.

In said drawing, A represents the gas-pipe, at which the gas enters either at a high pressure or sometimes at variable pressures, and A represents thepipe from which thegas escapes at low, regular, and uniform pressure. The gas-pipe A has the stop-cock B, the plug B of which is horizontal and is provided with a long handle, 13*. From the stop-cock B the gas passes through a T, O, in the bottom of which is inserted a petcock, c, to draw off condensed moisture. Upon the middle or vertical branch of the T is secured the cup-shaped bottom part, D, of my improved gas-regulator. This part D supports vertically a pipe, E, which may be twelve inches in diameter and forty-eight inches in length. Upon the central orifice of the bottom part, D, is vertically secured a pipe, G, which may be four inches in diameter and about the same length as the pipe E. Over the pipe G is placed a 5o bell or pipe, F, which may be eight inches in diameter, and its upper end must be closed.

Serial No. 199,598. (No model.)

This bell F is suspended from one end of a chain or rope, H, that passes over guide-pulleys I I, aud has its other end secured to a handle, 13*, of the stop-cock B.

The pulleys I I are retained in suitable journals secured to a support,K, (shown as attached to the large pipe 15,) but they may be otherwise supported.

The lower end 'of the bell F dips in a suitable liquid seal placed within the pipe E, so that the gas will not escape into the air.

Upon the handle or lever B of the stopcock B is placed a weight, b, that may be adjusted thereon and retained in any desired position by a thumb-screw bearing upon said handle. By moving the weight b backward and forward upon the handle B the desired pressure can be given to the gas.

When there is a high pressure of gas, the bell F is elevated and thus allows the weight b to press the lever or handle B down, and close or nearly close the stop-cock B; but if there is only a, small pressure of gas in the pipe A the bell F will descend and pull upon the rope H, thereby raising the lever B and opening the stop-cock B and allowing the gas to flow more freely through the pipe A.

The greater the weight b, or the farther it is from the fulcrum, the less will be the pressure of gas required to raise the bell F, and the less the pressure of the gas flowing out from the pipe A.

If at any time it is desired to increase the pressure of the gas flowing out from the pipe A, the thumb-screw on the weight b will be loosened, and the weight b will be pushed nearer the fulcrum of the lever B. This will require more pressure of gas in the bell F to raise it, and consequently will give greater pressure in the pipe A or, in other words, as the pressure of the gas issuing out from the pipe A is governed entirely by the weight of the bell F, and as the weight 1) acts as a counterpoise to the weight of the said bell F, the greater the force with which the weight b presses downward the less will be the pressure which the weight of bell F, can communi cate to the gas flowing out from the pipe A.

What I claim as my invention, and desire to secure by- Letters Patent, is

A gas-regulator connecting gas-supply pipe A with u gas-distributing pipe, A and 0011- upon said pipe A, substantially asshown, and sisting of a T placed between such pipes, arm for the purposes described. 1o rying cup D, supporting the pipe E and the In testimony whereof I affix my signature 1n interior pipe, G, and provided with a movable presence of two Witnesses.
